Hosta plant named ‘Beckoning’

ABSTRACT

A new and distinct  Hosta  plant named ‘Beckoning’ characterized by heat-shaped, large-sized, leaves with blue-green margins, yellowish leaf centers, tall vertical flower scapes with many near white flowers held nicely above foliage, suitable for landscape, potted culture, or cut flower arrangements.

Botanical classification: Hosta hybrid (Tratt.).

Variety denomination: ‘Beckoning’.

SUMMARY, BACKGROUND AND ORIGIN OF THE PLANT

The new and distinct Hosta plant, hereinafter also referred to as ‘Beckoning’ and “the plant” is a new and distinct cultivar of hosta. It was found by Timothy Saville in 1998 as an un-induced whole plant sport of the Hosta cultivar ‘Blue Angel’ (not patented) in a now defunct nursery in Cheshire, England. The plant has been successfully propagated by division and tissue culture methods at a perennial plant nursery in Zeeland, Mich. and found to produce identical plants that maintain the unique characteristics of the original plant. The plant is stable and reproduces true to type in successive generations of asexual reproduction.

Hosta ‘Beckoning’ differs from its parent sport, ‘Blue Angel’, all other known sports of ‘Blue Angel’ as well as all other hostas known to the applicant, in that the plant is variegated with a lutescent gold center emerging in the spring as nearly solid colored and gradually developing the yellow center with warmer temperatures. Hosta ‘Blue Angel’ also has some other sports including: ‘Earth Angel’ (not patented), ‘Guardian Angel’ (not patented), and ‘Fallen Angel’ (not patented). ‘Beckoning’ has a blue-green margin with a gold center of each leaf. Hosta ‘Guardian Angel’ has a blue green margin but the center is a misted whitish-green that tends to become all green in the heat of the summer. ‘Fallen Angel’ has the same whitish-green misting as ‘Guardian Angel’ through the entire leaf and does not have the solid blue-green margin. ‘Earth Angel’ has a creamy-yellow margin that is lighter than the center of ‘Beckoning’, and has the same blue-green in the center that ‘Beckoning’ has on the margin. The most similar known hosta cultivars in color are ‘June’ (not patented) and ‘Paul's Glory’ (not patented). ‘June’ grown in the shade has a similar color pattern as ‘Beckoning’ grown in the sun, but the new plant is between two and three times the size of ‘June’ in habit, clump height and width as well as leaf size. Hosta ‘Paul's Glory’ is slightly smaller in size of leaf and clump dimensions, and similar in colors, but the margin is less distinct, or more defused between the margin and center of the leaf on ‘Paul's Glory’ and more distinctly featured or jetting on ‘Beckoning’.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the overall appearance of the plant, including the unique traits. The colors are as accurate as reasonably possible with color reproductions. Ambient light spectrum, source and direction may cause the appearance of minor variation in color.

GENERAL DESCRIPTION OF THE PLANT

The genus Hosta is mainly native to Japan with a few species originating from China and Korea. There are over 3,300 cultivars registered with The American Hosta Society, which is the International Cultivar Registration Authority for the genus Hosta. Hosta ‘Beckoning’ differs from all of these in that it has:

-   -   1. Rugose pointed heart-shaped leaves with blue-green margins         and gold centers     -   2. Large plant size in clump habit and leaf dimensions     -   3. Tall scapes with many light lavender flowers.

DETAILED BOTANICAL DESCRIPTION

The following descriptions and color references are based on the 2001 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. The new plant, Hosta ‘Beckoning’, has not been observed under all possible environments. The phenotype may vary slightly with different environmental conditions, such as temperature, light, fertility, moisture and maturity levels, but without any change in the genotype. The following observations and size descriptions are of a four-year old plant in a garden in Stockport, Cheshire, United Kingdom.

-   Botanical classification: Hosta×hybrid. -   Parentage: naturally occurring sport of Hosta ‘Blue Angel’ (not     patented). -   Propagation:     -   -   Method.—By tissue culture and division.         -   Time to initiate roots from both division and tissue             culture.—Two to three weeks.         -   Rooting habit.—Normal, fleshy, lightly branching. -   Plant description:     -   -   Plant shape and habit.—Hardy herbaceous perennial with basal             rosette leaves, symmetrical and arching over.         -   Crop time.—Under normal growing conditions about 18 weeks to             finish in a one-liter container. Plant vigor is good to             high.         -   Plant size.—Foliage height at flowering is 45 to 55 cm tall             from soil line to the top of the leaves and 50 to 60 cm             wide. -   Foliage description:     -   -   Shape and size.—Cordate leaf blades have an acute apex and             auriculate base. The leaf blades are 30 to 35 cm long and 25             to 30 cm wide. The leaf blade margin is entire and the             variegation pattern on the edge varies in different regions             of the leaf from 10 to 25 mm wide. The leaves have between             16 and 18 pairs of major parallel veins.         -   Blade color.—Young emerging leaves. Top surface margin and             center: RHS 137C; Underside margin and center: RHS 191 B.         -   Top surface of mature leaves while still containing glaucous             wax.—Top surface margin: RHS 119A and RHS 116 D. Top surface             center: more yellow than RHS 144B. Underside margin: more             blue than RHS 189A, and more gray than RHS N138A.

Bottom             surface centers: between RHS 147C and RHS 147D before the             wax is lost, and RHS 160B after loss of the glaucous wax. -   There are two or three intermediate and inconsistent color patterns     between the center and the margin. The most prominent intermediate     color bands on the top surface are RHS 136 C and RHS 133 C.     -   -   Veins.—The 16 to 18 prominent veins pairs, while depressed             on the top surface and slightly protruding on the bottom,             are the same color as the surrounding leaf tissue in all             observed conditions.         -   Petioles.—30 to 45 cm long and 1.5 to 2.0 cm wide.

The plant grows best with plenty of moisture and     adequate drainage, but is able to tolerate some drought when mature.     Hardiness at least from USDA zone 3 through 9, and other disease     resistance is typical of that of other hostas.
